Question

Rosa eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mostly starch. Rosa plans to go for a run later this afternoon. Rosa is breathing normally.What does she need from the food she ate and the air she breathes so that she can go on her run? How do Rosa’s body systems work together to get the molecules she needs into her cells? How do her cells use these molecules to release energy for her body to run?​

Answer:1 2 look at my shoe 3 4

Explanation:so this is the gamer move

Answer 2

Answer:

1) Rosa needs glucose from the food she ate and oxygen from the air she breathes

2) She firstly undergird digestion, which breaks down the food into glucose. The glucose is absorbed by each cell

3) Her cells produce energy via the process of cellular respiration

Explanation:

To perform any activity, cellular energy in form of ATP is needed. However, this energy is derived via a process called CELLULAR RESPIRATION, which uses the products of digestion of the food we eat and oxygen.

According to this question, Rosa eats a peanut butter sandwich for lunch and plans to go for a run later in the afternoon.

1) To get energy which is needed for her run, Rosa needs glucose from the peanut butter sandwich she ate and oxygen from the air she is breathing to synthesize this energy.

2) The peanut butter sandwich first undergoes digestion i.e. breakdown into glucose, which is then absorbed by her cells in order to use. Oxygen from air is taken in by the lungs and diffused into her cells. In a nutshell, digestive system and respiratory system works together to carry out this task.

3) The cells use the oxygen and glucose in a process called CELLULAR RESPIRATION to produce energy (ATP). This occurs in three stages namely: glycolysis (occurs in the cytoplasm), Krebs cycle and oxidative phosphorylation, which both occurs in the mitochondria.
